Abstract (en)

A pixel circuit, a method for driving a pixel circuit, and a display device are provided. The pixel circuit (100) includes: a storage circuit (11), a data writing circuit (12), a light emitting driving circuit (13), and a compensation circuit (14). The data writing circuit (12) is connected to the storage circuit (11), and is configured to write a data voltage to the storage circuit (11) under control of a scanning control signal; the storage circuit (11) is configured to store the data voltage and enable a stored data voltage to be available to the compensation circuit (14) for a compensation operation; the compensation circuit (14) is connected to the light emitting driving circuit (13), and is configured to maintain a compensation voltage based on the stored data voltage at a control terminal of the light emitting driving circuit (13) under control of a compensation control signal; and the light emitting driving circuit (13) is further connected to a light emitting element (EL), and is configured to drive the light emitting element (EL) to emit light under control of the compensation voltage.
